When part 12, the voltage of the first measuring cell 210 and the second measuring cell 220 just falls in the section of 1200mV to 1600mV,
And then the measurement accuracy of range of lift measurement group 200.Or judged whether by the voltage that the first measuring cell 210 is incuded
Whether the distance between the first measuring cell 210 and the second measuring cell 220, which are located at preferable voltage distances, is converted position, to mention
Rise the precision of the workpiece to be measured 13 of the subsequent unknown width of measurement.
In addition, 220 magnetic force size of the second measuring cell will affect the range in different voltages section, and it is located at different voltages
Worst error of the distance corresponding to section at a distance from actual measurement.Specifically, according to the stronger magnet of magnetic force as second
Measuring cell 220, although the range shorter of each voltage range, be located at different voltages section corresponding to distance and actual measurement away from
From worst error also reduce.On the contrary, according to the weaker magnet of magnetic force as the second measuring cell 220, although each voltage
The range in section increases, but is located at worst error of the distance at a distance from actual measurement corresponding to different voltages section and also increases therewith
Add.Therefore, when selecting the magnet as the second measuring cell 220, it is necessary to therefrom obtain balance.
